It's not a matter of being "considered" silver, because a coin either contains silver or it doesn't.
Among common coins, the following were made of 90% silver:
> Dimes, quarters, and half dollars dated up to 1964.
> Large (38 mm) $1 coins up to 1935
40% silver:
> Half dollars 1965 to 1970
35% silver:
> Nickels 1942 to 1945, with a large mint mark letter over Monticello's dome. Note that NO other nickels ever contained silver.
Among 19th-century coins, strange denominations such as half-dimes, double-dimes, some 3¢ pieces, and Trade Dollars were also made of silver.
Dimes and quarters minted since 1965, halves since 1971, and dollars 1971-1999 are made of copper-nickel and don't contain any silver.
That's kind of a broad question. The best antique coins might be considered the rarest of coins and in that case the older the better. Coins from the medieval times or even ancient Greece might be considered the best.
All coins come from a mint. Casino coins are sometimes solid silver.
No British circulating coin has contained any silver since 1946. From 1919/1920 to 1946, all British silver coins contained 50% silver. Prior to 1919/1920, all British silver coins were made from sterling silver or, 92.5% silver.
No simple answer, many US silver dollars are considered rare for different reasons, be more specific and post new question.
There were proof sets made in 1974 and 1975 where all 8 of the coins were silver, and proof sets made during those years when none of them were silver. Assuming that your coins are in a set, check the 1 Cent coin - if it looks silver, then all the coins in the set are silver; if it looks bronze, then none of the coins in the set are silver.
Just recently with the advent of bullion coins such as the American Silver Eagle. Coins intended for circulation were never 100% silver because silver is simply too soft of a metal for coinage. They were 90% silver in American coins until 1964 for dimes, quarters and half dollars, but other than bullion coins, no coins are made of 100% silver.
Silver coins are typically shinier and have a higher metallic sound when dropped compared to pewter coins. Silver coins are also heavier than pewter coins due to their higher density. Additionally, silver coins may have distinct markings or engravings indicating their silver content.
999 silver is considered to be fine silver, meaning it is 99.9% pure silver. This high level of purity makes it a popular choice for investment-grade silver products such as bullion bars and coins.
The only U.S. coins currently made that are silver are American Silver Eagles and other special collectors coins sold by the U.S. Mint. These coins are NOT released for circulation.
No, the majority of them are genuine coins. Until 1967 the Mexican peso was partially silver (though, in 1967 it was only 10% silver) and all the peso coins dated 1967 and earlier contain some silver. Since a lot of them were made, most are not replicas and they are genuine coins. Since many of them were made and they aren't considered to be very attractive and rare coins, they are usually sold for little more than their silver content. Though there are a few replica pesos, the vast majority of them are genuine.
"Pure" silver coins were never minted in Britain. The closest to pure silver used in coins is sterling silver which is 92.5% silver usually alloyed with copper. Sterling silver coins were last issued for general circulation in 1919 and 1920, beyond 1919/1920 the coins were debased to 50% silver. The Royal Mint still produces Proof and bullion coins (not for general circulation) which are made from sterling silver, but this is reflected in the price you pay for them.
Yes they are silver
